Republican presidential hopeful Ohio Gov. John Kasich plans to announce Wednesday that he is dropping out of the race, accordion to multiple reports.

His campaign said that he will be making the announcement in a 5 p.m. speech in Columbus, Ohio.

The governor had scheduled a press conference outside Washington for Wednesday morning but abruptly canceled it and announced that he would be making a statement in later in the day.

Mr. Kasich, who has only won the Ohio primary in the race, is the only remaining rival to presumptive nominee Donald Trump. Sen. Ted Cruz of Texas dropped out of the race Tuesday night after the billionaire businessman’s landslide victory in the Indiana primary and opened a clear path to the nomination.

Despite Republican National Committee Chairman Reince Preibus declaring Mr. Trump the presumptive nominee, the Kasich campaign had vowed to press on in an attempt to force a contested convention.

He has been mathematically eliminated from winning the nomination outright and pinned his presidential ambitions on receiving the nomination after multiple ballots at a contested convention.
